AI API Router Directory

Microsoft Designer (designer.microsoft.com) is Microsoft's free AI design/image-generation web app (DALL-E based) for personal Microsoft accounts. Free users get a limited number of fast generations (boosts) - historically 15/day, with later region/account-specific limits reported (~60/month). This route is an unofficial, reverse-engineered web integration that captures the short-lived Bearer access_token from the DallE.ashx GetDallEImagesCogSci request; tokens expire quickly and must be recaptured.

Free personal-account boosts only (no credit currency documented).

MiniMax China (minimaxi.com) is the domestic-facing platform for MiniMax's foundation models. It mirrors the global platform's model offering and OpenAI-compatible API but optimizes for mainland China compliance and billing workflows.

No public free-tier information found (researched 2026-08-29).

MiniMax's open platform prices large language models per token with a published input-length threshold: MiniMax-M3 is $0.30 per 1M input tokens and $1.20 per 1M output tokens for prompts up to 512K input tokens, described as a permanent 50% discount off $0.60 / $2.40, and doubles to $0.60 / $2.40 above 512K. M2.7 is $0.30 / $1.20 with prompt-cache reads at $0.06 and writes at $0.375 per 1M tokens; a Priority service tier costs 1.5x standard. The same account also bills video, speech and image work separately, for example H3 video at $0.08 per second in 768P, speech-2.8-hd TTS at $100 per 1M characters and image-01 at $0.0035 per image.

No free tier or free credit stated on official pages (checked 2026-09-16); the documented entry points are prepaid Credits (1,000 credits = $1, packages from $5) and Token Plans from $22 per month.

ModelScope (魔搭, modelscope.cn) is an open-source model and dataset community founded in June 2022 by the Institute for Intelligent Computing together with the CCF Open Source Development Committee, organised around 'Model-as-a-Service'. The platform publishes models, datasets, Studios (application display space), MCP and Skills listings, and maintains the ModelScope, Swift, EvalScope and ModelScope-Agent frameworks. Its stated free offering is platform credits: 'Sign up / Log in to get 200 Magicubes' plus 'Link Alibaba Cloud account, get 50 more daily', with Studios described as 'a free and flexible AI application display space'.

No cash value stated: the official home page says 'Sign up / Log in to get 200 Magicubes' and 'Link Alibaba Cloud account, get 50 more daily' (modelscope.cn, checked 2026-09-16); Magicubes have no published CNY or USD rate.

Modeloc (modeloc.com) is an evaluation and compute-sharing platform for LLM relays. It features a 'compute pool' where users can share spare model quota to earn credits or spend credits to call pooled models, integrated with a trust-score leaderboard.

Compute-pool swap: deposit your own account quota, billed by usage; guests get free model-consistency checks only. Referral grants both sides ~100K compute (~$10) one-off — not a public free API tier.

MonsterAPI (monsterapi.ai) was an AI compute and model deployment platform. The service permanently shuttered operations on June 30, 2026, and its domains are no longer active. Details were checked against the provider's own page at www.crunchbase.com.

No free tier — the source marks this service as deprecated/discontinued.

Morph (morphllm.com) is an AI provider focusing on agentic coding models. Its API offers high-speed code editing and search via proprietary models (Compact, Reflexes) and optimized frontier models (GLM, Kimi), with a limited free tier of 200 requests per month.

Free tier is rate-limited (40 RPM default, 200 on request) rather than credit-based — no USD value to quantify.

Nebius sells two products relevant to an API-pricing decision: Token Factory, an OpenAI-compatible inference API for open models (where each model is offered in a default and a -fast flavor with different latency and token pricing), and GPU instances billed per GPU-hour, from $2.15 for preemptible H100 up to $7.85 on-demand for HGX B300. The public pricing page documents instance, storage and network rates plus billing rules; Token Factory per-token prices are only shown after login. Commitment reservations are advertised at up to 35% below on-demand rates.
